The DASH Diet (Dietary Approaches to Stop Hypertension) is a simple, evidence-based eating plan designed to lower high blood pressure and support heart health. It focuses on fruits, vegetables, whole grains, lean proteins, and low-fat dairy. DASH also supports weight management, blood sugar control, and long-term wellness.
What Is the DASH Diet?
The DASH Diet is a clinically proven nutrition plan created by the NHLBI, part of the NIH, to reduce hypertension and improve heart health. DASH emphasizes low-sodium, nutrient-dense foods while limiting processed foods, added sugar, and unhealthy fats. It’s safe and effective for anyone wanting to eat healthier.
Key Principles of the DASH Diet
Eat More Of:
Fruits & vegetables: Provide potassium, magnesium, fiber, and antioxidants.
Whole grains: Brown rice, oats, quinoa, and whole-grain bread.
Lean proteins: Fish, chicken, beans, nuts, and legumes.
Low-fat dairy: Milk, yogurt, and cheese.
Healthy fats: Olive oil, avocado, and seeds.
Limit:
Sodium: ≤2,300 mg/day (≤1,500 mg/day for best results).
Saturated and trans fats: Fatty meats, fried foods, and full-fat dairy.
Added sugars: Limit desserts and sweetened drinks.
Highly processed foods: Chips, canned meals, and fast food.
How DASH Helps
The DASH Diet works because it emphasizes nutrients that support healthy blood pressure and overall cardiovascular health:
Potassium, magnesium, calcium: Regulate blood pressure and improve artery function.
Fiber and protein: Help with satiety, weight management, and blood sugar control.
Low sodium: Prevents fluid retention and reduces strain on the heart.
Studies show combining DASH with reduced sodium intake lowers both systolic and diastolic blood pressure more than either approach alone.
A review of 17 clinical trials with 2,561 adults showed that following the DASH Diet lowers blood pressure compared with usual eating habits.
On average, systolic blood pressure dropped by 6.7 mmHg and diastolic by 3.5 mmHg. Even these moderate drops can reduce the risk of heart disease and stroke. PubMed

Health Benefits
1. Lowers Blood Pressure
DASH consistently reduces systolic and diastolic blood pressure, often within 2–4 weeks.
2. Supports Heart Health
Reduces LDL cholesterol, improves artery function, and lowers heart disease risk.
3. Helps With Weight Management
High-fiber foods increase fullness and support gradual weight loss.
4. Blood Sugar Control
Improves glycemic control and supports healthy insulin response in type 2 diabetes.
5. Reduces Other Risks
May lower risk of metabolic syndrome, stroke, and certain cancers.
Tips for Following DASH
Start Slowly: Swap refined grains for whole grains.
Check Labels: Watch hidden sodium in packaged foods.
Use Herbs for Flavor: Replace salt with herbs, spices, lemon, or vinegar.
Stay Active: Combine DASH with at least 30 minutes of daily physical activity.
